Couldn't find a forum for "Bugs", so as a feature...
When you have the timeline design history enabled, moves do not seem to be captured when a point to point move is used. This leads to errors if you rewind and replay a design history, because parts are not put into the correct place. This seems to happen if the move is a simple point to point, or a complex rotation followed by a point to point. (What I wanted to so was rotate a copy 180 degrees, then alingn a point to another feature.)
This does not happen when the move is a simple translation & rotation. Those seem to be captured in the timeline correctly.
